The Components of a Computer and Information Processing System
In today’s world, computers are everywhere. People use them in a wide range of ways in every aspect of life whether it is interacting with friends, cooking a meal, or transferring funds from one account to another. However, many people do not think about the many aspects of computing and the various devices and software that are part of the information process.
Basics of the Computer
A computer is a device that can be programmed to perform a specific operation. Computers take input from human operators and process it into something the user can see on an output device (Computer, 2012).
Hardware and software are what make up computers. Hardware is the physical aspect of a computer. The monitor, mouse, keyboard, and the computer itself would all be hardware. Software is the program that runs on a computer like Apple’s OS X Lion, for example. Software is usually thought of as something involved with computers but it can actually be used on other forms of hardware such as cell phones, GPS devices, or PDAs (Kayne, 2012).
Basic Components of a Computer
Computers today come in many different shapes and sizes. However, the basic components that make up computers are all generally the same. The computer case is where all the other components are stored. The brain of the computer is the CPU, or central processing unit. It is used to process all the functions the computer performs. RAM is where data is temporarily stored and accessed and is attached to the motherboard. The motherboard is the most important component; it connects all the other hardware in a computer system. A power supply sends the other hardware power so that they can run. Hard drives are used for permanent file storage. A disk drive can be a floppy drive, CD drive, DVD drive, or any other file storage devices that are used. Video cards are the parts that convert binary code into images so that the user can see it on a monitor. Monitors are the screens that allow users to see what the computer is doing. The keyboard and mouse are input devices that allow the user to enter text or point and click to enter commands, respectively (Basic Computer Components, 2011).
Information processing is a cycle. The sequence of events includes input, processing, output, and storage, in that order (Karbo, 2002).
Inputs and Related Hardware/Software
Input is the information that a person puts into a computer. Input can be in many different forms such as text, voice, or clicking. An input device is the hardware or software that a person uses to put information in the computer. The hardware might include keyboards, microphones, or a mouse (input, 2012).
Processing and Related Hardware/Software
When talking about computers, computing is referred to as an instance a computer program is executed. A computer program is a collection of instructions and a process is the actual execution of the...
